BED.

To @ZZ whom t ma'y concern:

Be it known that I, WILLIAM J. BosANKo, a citizen of the United States, and a resident of the borough of Brooklyn, in the county of Kings, in the city and State of New York, have invented a certain new and useful Improvement in Beds, of which the following is a full, clear, and exact description, reference being made to accompanying drawings, forming part ofthis specification.

This invent-ion relates to improvements in beds which comprise means operative to raise and lower the springs and support them in various positions, when the beds are occupied, and which are thereby especially adapted for use in hospitals and elsewhere in the treatment and care of invalids, the object of the invention being to provide for the attachment to beds of apparatus that will elevate and incline the springs so as to enable doctors and nurses readily to place patients in desired positions Without requiring them to exert any of their own strength or subjecting them to any strain.

The invention consists of the combination with a bedstead and bed-spring of apparatus which is hereinafter described and specified in the claims.

On the accompanying two sheets of drawings which illustrate the invention in its preferred form, and on which like reference-numerals designate like parts of different views: Figure 1 is a perspective view of the apparatus, shown in combination with a bedstead and bed-spring, some of the wire portion of the spring being omitted to avoid obscuring parts of the drawing; Fig. 2, an enlarged view of a screw which the apparatus includes, the bearing of the screw, and a nut and fragment of a link with which the screw co-acts, being shown in section; and Fig. 3, a side elevation of the bedstead, spring, and apparatus, that end of the spring which is next to the foot of the bedstead being shown elevated.

The bedstead and spring shown are of Well known construction, the bedstead comprising the pair of head-posts 1, the pair of foot-posts 2, and the side-rails 3, the posts 1 extending through the blocks 4 which are fast on the posts and to which is affixed the cross-bar 5, the posts 2 extending through the blocks 6 which are fast on the posts and to which is affixed the cross-bar 7, and the rails 3 fitting at their ends in recesses in Specification of Letters Patent.

these blocks, and the spring being composed of woven wire 8 attached to thel ends 9 of a frame comprising round side-rails 10.

The apparatus or attachment which is shown combined with the bedstead and spring comprises two pairs of levers, two operating-screws, two connecting links,

xed'sto-ps on the bedstead, and adjustable y they all being alike and preferably angular levers, has the arms 15 and 16, and the leversY of each pair are connected together at their ends by cross-rods 17 and 18, and on 'the cross-rods 17 close to the arms 15 of the levers are grooved rollers 19.

These rollers 11e under and fit against the side- :railsl 10 ofthe spring, and when the levers are 1n their normal positions, namely the positions which they occupy while the `spring rests at bot-h ends, as it commonly does, on the blocks 4 and 6 of the bedstead, lthe arms 15 of the levers that are mounted `on the cross-rod 11 extend from thatrod toward and nearly to the head of the bedstead, as appears by Fig. 3, and the arms 15 of the other levers extend from the crossrod 13 toward and nearly to the foot of the bedstead.

The operating-screws 2O are supported by cross-bars 21 fastened to the posts 1 and 2, each screw having a bearing 22 (Fig. l2) which is pivotally mounted on threaded pins 23, screwed into brackets 24 and scoured therein by nut-s 25, the brackets being affixed to t-he supporting cross-bar 21, and on each screw 20 are collars 26 that are fastened to it close to the ends of the bearing 22 by set-screws 27, and that prevent the screw from moving axially in the bearing. These screws 2O lit at their outer ends in the sockets of the hand-cranks 28, which are detachable from the screws. y

Each of the two connecting-links comprises branches 29 which are secured to the sides of a block 30 by screws 31 (Fig. 2) at one end of the link, and diverge from each other nearly to its other end. The screws 2O extend through holes 32 in the blocks 30 and through nuts 33 which are, pivoted within the blocks to the sides thereof and branches or' the links, each of these nuts being mounted on screw-threaded pins 3l on which are lock-nuts 35. These links are connected with the power-arms 1G of the levers by the cross-rods 1S which pass through the branches 29 of the links, as shown by Fig. l.

'lhe fixed stops on the bedstead are the pins 36 which project from the blocks t and 6, and the adjustable stops above mentioned are the clamps that are shown mounted on the side-rails l0 of the spring, each of these clamps 37 comprising parts between which the rail extends, a thuinb-screw 38 by which these parts can be drawn toward each other and against the rail, and a hook 3S) forming an extension of one of these parts.

To raise either end ot the spring from its normal position on the bedstead, the screw 20 under that end which is to be raised is turned with the crank so that the connecting-link is drawn toward the crank by the action of the screw on the nut 33, and as the link pulls the lower ends of the levers to which it is connected toward the adjacent end of the bed the arms 15 of the levers act on the spring through the rollers 19 and push the end of the spring up, its other end resting against the adjacent stop-piiis 36, and the rollers traveling along the rails 10 of the spring. That end of the spring which is next to the foot of the bed can be raised as described to the position shown by Fig. 2, or the other end can be raised to the corresponding position, and when either end is elevated to one of those positions or to a height less than that shown by Fig. 3, the elevated end is rmly supported by the levers acting through the connecting-link on the screw 20. rEhe spring can be raised from its normal position to that in which it is shown in Fig. l, by turning both screws at the saine time, or by elevating the ends of the spring alternately. To change the position of the spring from that shown by Fig. 3, for example, to a horizontal elevated position: Two of t-he clamps 37 are adjusted on the rails 10 at the places indicated by the lines 40, between the elevated end of the spring and the supporting levers, and there tightly secured to the rails; then the elevated end of the spring is lowered so as to force the spring toward the foot of the bed; and then the other end of the spring is elevated. after the levers that act on the hooks 39 of the adjusted clamps have forced the spring to such a position that its lower end as it rises will clear the adjacent upright portion of the bedstcad. The hooks of the adjusted clamps, extending under and acting on the rollers, prevent the spring from sliding after its lower end leaves the xed stop-pins. The spring will be prevented from moving endwise, when it is in the position shown in Fig. l, if the clamps are adjusted and secured on the rails 10 so that the hooks of the clamps engage the rollers of both pairs of levers.

It will be understood that the spring can be restored to its normal position, by lowering first one end and then the other, or both together, and that one person can raise it to the position shown by Fig. l, as well as many other positions, and can incline it to a greater or less extent from either the head or foot of the bed. In some cases it may be desirable to provide beds with apparatus to elevate each spring at one end only, and then the attachment to be applied to each bed will consist of but one of the pairs of levers, the means described for actuating them, and two ofthe fixed stop-pins.

The apparatus described can be easily adapted and applied to beds of diiferent sizes and styles, and the invention can be embodied in a combined bed, spring, and spring-elevating apparatus differing more or less in detailsor1 construction from that which has been specifically described herein.
